Two newlyweds, Penelope Reed and Wyatt West, have just finished their wedding reception at the house of Wyatt's stepdad, Derrick Pierce. When Penelope wants to get away to enjoy their wedding night, Wyatt insists they need to thank Derrick for all his help first.
Once they do, Penelope is shocked to learn that she is expected to have sex with Derrick instead of Wyatt on her wedding night. Derrick insists it's tradition for HIM to pass on his genes to his stepsons' wives, in exchange for making sure everyone's set for life. After some initial hesitation, she's eventually convinced, then has sex with Derrick in front of her husband.
